WRAPPING-MACHINE.

To all whom it may concern:

Be it known that I, @r'ro E. EnsTRoM, a citizen of the United States, and a resident of the city of San Francisco, in the county San Francisco. and State of California, have invented certain new and useful Improvements in mapping-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

My invention relates to a machine for providing acable with a loop or eye, and has roferenre more particularly to a machine for wrapping a wire around the portions of the cable at each side of the loop so as to fasten same together.

An object of my invention is to provide a machine for wrapping a wire around the cable and turned back end thereof so as to fasten same together and form an eye or loop in the end of the cable.

another object of my invention is to provide a machine for wrapping a wire around a cable and the turned back end thereof, in closely arranged soils which continue beyond the turned back end of the cable so as to bind the loose end of the cable firmly in place and make a strong neat connection.

Another object of my invention is to provide a machine for winding a wire around a cable and the turned back end thereof so as securely fasten same together and form an eye or loop in the end of the cable, the wire being automatically wrapped with spaced windings to permit soldering between sections of the wrapping wire.

Another object of my invention is to provide machine for winding a wire around a cable and the turned back end thereof, and having means for automatically removing a clip or tie on the end of the turnedbaelr portion of the cable as the winding approx- 7 imates this point.

As shown on the drawings:

The supporting frame for this machine is shown herein of a pipe construction and comprises the standards 1 and 2, with foot plates 3 for securing the machine to the partly in section on the 7 floor. At the upperend of the standards 1 and 2, are the brackets 4, 4 and 5, respectively, each of which hasan eye at each side thereof engagedby and securedtothe parallel longitudinal frame members 6, flJflyfl each also has an intermediate elevated hearing within which are journaled the tubular shafts hereinafter described. The brackets 4 and 4, between which the winding mechanism islocated, are also provided with the intermediate bearings 8, with the bushings 9 and 10 therein within which is journaled the shaft 11. The brackets '4, 4 and 5 may also be connected to the floor by meansof turnbuckles 12 and rods13, shown in Fig. 3, to hold the machine firmly in position.

Journaled in the end bracket 4 and an intermediatebracket14, which latter is carried by the longitudinalframe members 6, is a tubular having anopening therethrough, through which the cable operated upon and the loop end thereof may be drawn,

and the bearings of the brackets 4 and 14, V

which support this hollowshaft 15, are provided with bushings 16, which are held 1n place by the bearing caps 17, with which the bearings are provided to-permit adjustment and replaeementof the. bearings. At the inner side of the bearing 14 the hollow shaft 15 has the, chuck head 18 threaded thereon, asshown in I 6, or otherwise secured on .the shaft 15, and affording a shoulder engaging the bearing 14 to hold the shaft 15 from endwise movement, and there is a large gear 19, secured on the shaft 15 and engaging the opposite side of thebearing 14 to hold the shaftfrom endwisemovement inthe opposite direction. A driving pulley 20, is also mounted on the shaft 15, and is connected with any convenient source of power so as to operate the shaft 15 in the direction indicated by the arrow in Fig. 4. Mounted in alinement with the hollow shaft 15 is another hollow shaft21, which is journaled in the upper bearings in the brackets 4, 4 and 5', which said bearings also ha vs the bushingsj22, heldxin place by bean ing caps23. This'hollow shaft 21 is adapted to contain the cable to be operated on, and in order to accommodate cables of various lengths, othernstandards 21and brackets 5 may be provided in addition to those shown in the drawings,and the shaft 21 andframe members 6 are constructed with couplings 24 and 25, respectively, to permit increase, or

decrease in the length of the machine so as 1 lengths,

to enable it to be used with cables of different The hollow shaft 21 is mounted to slide lengthwise in the supporting bearings, and

adjacent the inner end is supported in a pair of spaced bearing brackets 26, which are carried by the frame members 6. i The bearings for the shaft 21, in these bracket-s 26, are provided wlth the bushings 27, similar to the other bearings hereinbefore described and have the sleeve 28mounted to rotate therein and provided with a collar 29 at each end engaging the outer face of the adjacent bearing. The shaft 21 is inserted through the sleeve 28 and has a long key or spline 30 slidably engaging a keyway in the sleeve 28,

so that the shaft is caused to turn with the sleeve and may slide endwise in the sleeve, and there is a gear 31 fastened on the sleeve 28, between the bearing brackets 26, by means of a set screw or inany other suitable manner. The gear-Eli's of the same size as the gear 19, previously described, and is operated therefrom by means of the countershaft Y 7 38, which is journaled in the bearings 84, at

' the rear of the machine, and has a pinion 35 at each end of the same size meshing with the gears 19 and 31, so that when the shaft 15 is rotated the shaft '21 is likewise rotated in the same direction and at the same rate of 7 speed.

The inner ends of the shafts 15 and 21 are separated a suflicient distanceto properly position the clutch members or cable holding mechanisms 'with which the inner end of each shaft is provided for holdingthe loop end of the cable which is to be wrapped, the clutch on the first mentioned shaft being adapted to grip the loop end or eye of the cable, and the clutch of the latter shaft being adapted to'eingage the cable and turned back end thereof. e v

The end of the cable which is to be formed withthe eye or loop is cut diagonally so as to provide an inclined end, and afford a neat joint in the finished product, and the cut end is temporarilyinclosed in a'retaining cap or clip 37, or may be wrapped with wire or otherwise held toprevent spreading or unwinding of the cable strands. thimble 38 is placedin the looped end of the cable and the cable held around the thimble, during; the

wrapping operation, by the chuck with which the shaft 15 1s provided. This chuck comprises an end plate 39, which is secured to the head 18 by means of the cap screws 40,-and is centrally perforated at 41 to permit the cable tobe drawn therethrough, and the portion.

of the plate, which is cut away to afford the opening 41, is bent outwardly, as at 42, to a support the plate 48, on which the chuck mechanism is mounted. A stop or abutment plate 44 is (letachably mounted on the inner trically arranged with reference to the shafts 15 and 21. A. jaw 48 is pivotally mounted at each side of the plate 44 on pivot pins 49, the ends of which are connected by means of the strap 50, for the purpose of bracing the jaws 48, and plate springs 51, are mounted on the plate 43 to engage the inner face of each jaw 48, and press outwardly against same. The forward ends of the jaws 48 are bent inwardly as at 52, and each is notched on the end at 53, to engage the looped cable on the thimble 38 at points where the cable at each side of the loop 38 converges, so that when the jaws 48 are pressed together so as to engage the cable on the thimble, the thimble and cable thereon are forced into .engagement with the notches 47 in the arms 46 of the abutment plate 44, and the cable thereby drawn tight around the thimble 38 and the cable and thimble thus securely clamped in the chuck.

For clamping the arms or jaws 48 together there is a bar 54 at one side of the position occupied by the looped cable in the chuck, and extending through openings adj accnt the free ends of the jaws, as shown, the said bar 54 and openings therefor in the arms 48 being preferably rectangular or otherwise shaped so as to hold the bar from turning and permit movement of the said bar in the direction of its length through the said opening. A cam 55, having an operating handle 56, is pivoted at one end of the bar 54, and there is a collar 57 adjustably secured at the other end of the bar 54, both being arranged to engage the outer faces of the jaws 48, so that when the lever 56 is turned inwardly from the position shown in Fig. 7, to the position shown in Fig. 6, rotation of the cam 55 draws the free ends of the arms 48 together so as to clamp the cable and thimble in the chuck. For providing adjustment of the collar 57 to enable the jaws 48 to hold cables and thimbles of various sizes, one side of the bar 54 is toothed as at 58, and the collar 57 provided with an inwardly projecting lip 59, which may be engaged with the various teeth 58 of the bars 54, and held in such engagement by means of the set screw 60, which is threaded through the opposite side of the collar 57, against the back of the bar 54. The upper end of the collar 57 is offset at 61 to provide a wide engaging face to bear against the outer face of its jaw 48.

On the shaft 15, adjacent the outer end, is a hand wheel 79 to permit manual operation of the mechanism to permit convenient access to the parts. On the inner end of the other shaft 21, a ring 61 is secured and provided with diametrically opposite bearings 62, in which are pivotally mounted a pair of levers or arms 63, which reach forwardly beyond the end of the shaft 21, and are provided at the forward ends with internally turned linger 130, which, when the levers 63 are pressed-together to grip the cable, overlap and are separated substantially the width of the cable so as to hold the two portions of the cable to be bound together, side by side, as shown in Fig. 10, and these fingers 130 serve as strippers to automatically remove the end clip 37, or other fastening whlch' may be used to temporarily prevent unwinding of the end strand of the cable,

as the winding approaches that portion of the cable. I,

The levers 63 are pivoted intermediate of their ends as shown, and the ends thereof opposite the grippers 64 project back over the hollow shaft 21, so as to be engaged by the flange 131, of a collar 66, which slides lengthwise of the shaft 21. This collar 66 slides on a sleeve 67, which is secured to the shaft by a set screw 68, or in other convenient manner, and has a hand wheel 69 at the end thereof which may be used for turning the shaft 21 to facilitate access to the work, and a spring 70 is interposed between the hand wheel 69 and the collar 66, so as to normally .force the collar and flange 131 thereof to engage the rear end of the levers 63 and force the forward ends thereof inwardly to securely grip the cable. When the cable is to be inserted in place for wrapping, the collar 66 is retracted beyond the ends of the levers 63 and said levers tilted to the position shown in Fig. 11 and held in such position by the pressure of the collar flange 131.

In wrapplng the cable, the looped end thereof is held in the chuck on the inner end of the shaft 15, and the shaft 21 and gripping levers 63 thereon are gradually moved.

away therefrom at a rate corresponding with the advance of the wrapping wire on the cable. For this purposethe shaft 11 is provided with a worm or screw .71, and the shaft and .worm are driven by means of the gears 72, 73 and 74 from the shaft 15 at the proper speed to retract the shaft 21 in .the required manner. The rate of movement re quired of the shaft 21 depends on the size of the wire used in wrapping the cable, and as this wire varies in wrapping cables of different sizes, the gears 73 and 74 are detachable by removing the cap screws 75 and 76, respectively, and the intermediate gear 73 is mounted on a swinging bracket;

77, which is adjustable circularly on the sleeve extension 78 of the bearing 10, soas to permit the use of different sized gears to secure the proper rate of speed for the shaft 11 and worm 71. 1

each side of the open space therebetween are provided with the half clamps Maud half bearings 85, the former of which are secured tothe end of the tube 80 by means of the bolts 86, and the latter of which are held to loosely eniibrace the shaft 21 by means of the bolts 87. Longitudinal movement of the bearing 8585 on the shaft 21 is restricted by the CORR-F88 at one side, whichis secured on the shaft 21, and by means of the resilient collar-89 at the other side, which is likewise secured on the shaft 21.

The bracketconnection 82 normally con trols the longitudinal movement of the shaft2l, and is geared to retract the shaft 21 as nearly as possible in accordance with the winding of the wire on the cable. However, the gage of the winding; wire sometimes varies and necessitates a slight movement of the shaft 21 in advance of the movement normally imparted thereto by the gearing, andtheresilient collar 89 is provided to permit such advance movement to theshaft21. This collar, as is shown in Figs; 17 and "18, has an annular flange 90 atone end and a ring 91 embraced by the flange 90 and fitting loosely on the shaft 21. A plurality of plate springs 92 are secured to the ring 91and extend up from the surface thereof so that the free ends thereof engage against the col lar 89 inside the flange 90, and as the ring 91 abuts against the bearing I8585 of the bracket 82-82, and as the collar 89, is se cured to the shaft 21, by means of the set screw 93, a limited cndwise movement of the shaft 21, is permitted against the tension of the springs 92. i

A collar 9 1, is secured on the tube 80, at a distance from the bracket 82-82, and has the lever 95 pivoted thereto so that the end thereof extends between the half sections 82, of the bracket, and a tooth 96 is mounted onthe lever 95, and extends through a slot 97 in thetube 80, and has the inner end formed asat 98to engage the worm with the outer'end ofthe lever 9?, so that when the handle 100, is pressedinwardly,

the lever 95, is swung on its pivot andthe thread of the worm 71; mountcdbetween the half sections of the bracket 82, engages the lever 95to normally tion by means of the lock nut 111.

tooth 96, lifted from engagement with the A spring 101,

hold same downward so that the tooth 96 is in operativeengagement with the worm 71. 1

1n wrapping cablesit is desirable to provide gaps or spaces separating closely wound portions and this is effected with my device in the following manner. A. spring 103, of sufficient strength to move the shaft 21, and the parts connected therewith, has one end attached to the frame of the machine, as at 10 1, and, the other end to the bracket 82-82, by connection with one of the bolts 86, or in any other suitable manner, so that the engagement of the tooth 90, with the worm 7'1, holds the shaft 2;, and bracket 82-82, and parts connected therewith from movement under the tension of the spring 103. The worm 71, may he mutilated as a 105, and106, by having portions of the thread cutaway at these points, or if do? sired, the worm may be cut with the thread offset at the point required so that when the mutilated or offset portion of the thread reached by the tooth 96, the bracket 82-82 and shaft 21, and parts connected therewith are permitted to jump a short distance under the tension of the spring, 108, so as to afford the gaps or spaces 102 and 107, in the winding of the wire on the cable corresponding to the mutilated portions 105 and 106, respectively, of the worm.

For feeding the wire to be wrapped around the cable, there is an arm 108, mounted on the tube 80, and extending to a point adjacent the inner ends of the grippers 64:, which latter move along the portion. of the cable to be wrapped, and this arm 108 has an adjustable shoe or guide 109 secured to the end thereof by means of thothreaded stem 110 and locked in posi- This shoe tapered so that it may be adjusted in close proximity to the end of the grip pers 6 1, and has a groove 112, in the front face thereof to guide the wire on to the cable moves with the tube 80, so that its movement corresponds to'that of the shaft 21 and the grippers adjacent which the wire istobe wound, and said. arm may have an adjustable connection 113, for changing the position ofv the shoe 109, if required. v

Also supported on the tube/'80, so as to move therewith is the frame for supporting the wrapping wire comprising the arms 11%, which are'clamped on to the tube 80, and have the bearings 115 at the outer ends thereof to'support the shaft 116, on which the spool 117, of wrapping wire 118 is loosely mounted. The bearings 115 have the upper half sections thereof pivotally con nected with the lower half sections and detachably held to engage the shaft 116 by clamp nuts 118, which 7 may be readily opened to permit removal and replacement of the spool of wire. A round bar 119 is mounted between the arms 114, above the spool of wire so that the wire 118 may be looped thereabout one or more times to afford sufficient tension to wind the wire tight around-the cable, and a spring 120, i interposed on the shaft 116 between one end of the spool 117 and one of the bearings 115, and serves to afford a frictional resistance to the operation of the'spool 117 to afford tension to the wire 118. The connection of the arms 114 of the wrapping wire support with the tube 80 is sufiiciently tight to insure movement of the wrapping wire supporting frame with the tube, and at the same time permit the frame 114 to be swung upwardly around the tube 80 to provide sufficient wire for making the connection with the cable in starting the wrapping operation.

The operation is as follows:

The machine is first set up for the size of cable and wrapping wire which is to be used, by providing a plate 44 of suitable size for the end of the loop to be formed,

, and by adjusting the collar 57 to properly clamp the loop in the chuck. The stripper fingers 130, are also adjusted laterally to accommodate the width of the cable to be wrapped. The gears 73 and 74, are changed if required, to drive the worm 71, at the speed required to move the wrapping mechanism as the cable is wrapped, the rate of speed being determined by the gage of the wrapping wire employed. The cable is previously cut in a diagonal direction and provided with a retaining cap or clip 37, or other means for retaining the ends of the cable from spreading or unwinding and the end of the cable is bent back at the point where the loop is to be made and so that the beveled face at the end-of the cable faces outwardly. The jaws 48 of the loop chuck are opened, as shown in Fig. 7 and the levers 63, are opened up as shown in Fig. 11. The looped end of the cable is then inserted through the pipe 21, and the thimble 38, fitted into the looped end of the cable, and the thimble and cable *thereon is then clamped between the j aws-48 and the abutment plate 44, by swinging the hand lever 56 rearwardly to the position shown in Fig. 6. j

The wrapping wire carrier 114 is then raised slightly to advance the wrapping wire 118 sufliciently so that the end may be caught in any convenient manner at the inner end of the thimble 38, so that when the cable is rotated the wire 118/will be wrapped therearound, and the wire is laid 1n the groove 112 of the wire guide 109, and the wrapping wire frame114 permitted to-swing down to the normal position. The levers 63, are then tiltedforwardly so that the stripping plates 65 are on opposite sides of the two portions of the cable to be Wrapped, and thegrippers 64 engage the two portions of the cable to be wrapped immediately adjacent the inner end of the thimble 38, care being taken that the wrap ping wire 118 is beyond the ends of the grippers 64, so that it will be wound on the cable. The forward tilting of the levers 63 releases the rear ends of said levers from engagement with the front face of the flange 131, :of the'ring 66, and the tension of the spring forces the ring under the rear ends of the levers and automatically clamps the forward end thereof in engagement with the cable. I

The machine is then thrown into opera-- tion by applying power to the pulley 20, to rotate the'shafts 15 and 2-1 in the direction indicated by the arrows in Fig. 4, and the cable and portions thereof to be wrapped are caused to turn with these shafts. As the shafts and cable rotate the wrapping wire 118 is'wound on the two portions of the cable which are to be bound together, being guided thereon by the shoe 109, and also by the ends of the gripper 64, so that the wrapping wire is wound in a close tight coil. As the wire is woundon the cable the pointof application continually advances at a rate depending upon the gage of thewrapping wire employed, and as the gears 73 and 74 operate the worm 71 so as to permit-advance of the shaft 21 and hollow tube at' the same rate'of speed,

the wrapping wire will be fed on to thecable so as to provide a close tight coil except at the places where the gaps are to be provided for soldering. I

When the worm 71 has turned sufficiently so that the tooth 96 reaches the point where the thread of the worm is broken. away, the spring 103 causes the shaft'21, tube 80 and parts connected therewith to jump a d1stanceuntil the tooth 96 reengages the thread, thus affording a 1 gap or unwound place between closely wound COllS of the winding wire, for soldering to insure a tight hold of the winding wire on the portions of'the cable wrapped thereby. The points at 'whichthe open places inthe winding are to be provided depend upon the location of the places in the. worm where the thread is mutilated or offset, and the Worm may be constructed to provide any number of un- [wound placesfand spaced in any desired manner.- V Whenithe cable is wrapped as far as required, the machine .is' stoppedgan'd the clutches released,iandthe wrapplng wire 118,

, holding the article to be wrapped, and means cut off at the end of the wrap, whereupon the loop just made may be moved to one side to pass the arms 46 of the plate44c, and inserted through the opening 41 in the plate 39, and drawn out through the hollow pipe 15, the cable at such time passing freely between the armstG of the plate 44.

To reset the machine, the lever 100 on the bracket 82 is pressed inwardly, thereby lift ing the lever 95 and the tooth 96 from engagement with the worin,and the shaft 21 and tube 80 and partsconnected therewith may bemoved back to the starting position.

While I have shown and described my invention in a preferred form, I am aware that various changes and modifications may ,be made therein without departing from the principles oi my invention, and I therefore do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art. i I claim as my invention V 1.
